CHALLENGES

• With only one entrance into the estate, JLES engineers had to continually monitor and manage the traffic flow accessing and exiting the development.

• The excavations crossed many residents' driveways, so road plates and extensive liaisons were completed to ensure access was available when required.

• Engineers had to carefully work around difficult utility crossings within the highway when completing a full length re-lay of a foul water sewer.

• Due to the depths of the excavations, we faced multiple complex health and safety issues, which meant JLES engineers had to ensure they were always working to the correct regulations.
